Hello all. I recently purchased an LG G2 VS980 second hand. I've got a question about the camera. I'm wondering if the camera in the unit I have is defective, or if that's just the way it is. It seems that any photo's I try and take with unnatural light, involve massive over exposure of that light if it's nearby and loss of detail. Lowering the exposure and iso setting does not compensate enough for this problem, either does trying HDR mode. I have enclosed a photo taken with a Nexus 5 which properly handles a particular scenario throne at it, as well as the same shot taken with the LG G2. There's a big difference between the two, and this is not what I was expecting given everything I've seen in terms of the G2's photographic capabilities. What are your thoughts? I have tried taking photo's on the G2 with the stock camera as well as Google's camera, but I could come nowhere close to the nexus 5 in terms of detail.

Solved, and nearly unbelievable to me. This problem seems to have occurred because the camera lens cover had "scratches" on it that were hard to see. Actually they were not scratches, but just a crappy oleophobic coating applied to the lens cover by LG that gave the appearance of scratches. To fix this, I disassembled the phone and removed the plastic cover that housed the camera lens cover. I then followed the instructions in another thread and used toothpaste and q-tips to clean the it. The difference in photo quality is astounding and now the photos of my lamps match or surpass what I was getting from the Nexus 5. It was very time consuming though to get it cleaned using the toothpaste method. Instructions for anyone else having this issue can be found in the following thread. I suggest though, if you need to do the cleaning, you also remove the plastic housing containing the lens cover from the phone as shown in this youtube video so that you don't accidentally get water or anything else dripping into the inside of the actual phone. I actually also used some distilled vinegar for cleaning and that may have worked better than the toothpaste.

Anyone else noticed some kind of lens reflection problem at night photos?
Hope it's not design fault.
There's no scratches at lens and phone is only two weeks old!
Sample pictures attached:
Edit: yes lens flare is norma, but is it really normal that effect is so strong?
Take that same exact picture with a real digital camera and compare it before posting up another "issue" thread.
Seriously, people are picking straws now.
That's a known optical phenomenon which is called "FLARE". edit the title, this might get people anxious.
Lens flares is a problem optics struggle with. Even 1500 dollar lenses fail in this. But with special coating and sofisticated technology it can be less flares.
The only real solutions to prevent flares are:
a) dont point the lens to a direct light source (like the sun)
b) use a lense hood (on a phone?? hehe)
But you can in fact use your hand to shadow the lense to prevent this.

My take on this:
Since night mode compensates with high ISO, it will get those lights more. Try covering the bright part.
This is absolutely normal for cheap camera with a very small lens and plastic cover.
high iso wont likely give you more flares, just more noice. Unfortunatly with almost all but real slr´s the software tries to hide this noice with cheap and lousy smooth-filters, creating a soft and cartoonish look
Hi
I have the lg g2 for a week and I have to say that's find it very hard to get good pictures, the colors are not great (seems like the camera is not taking the light well) and it is very hard to get non blurry images with any small movement in general and specially when starting to work with the zoom
I read in this forum that I should check if I have some bluish/purple coat on the lens (looks like a sticker) and I actually do have it but I did not understand if this is the cause of the problem and I should remove it or.....
I have to say that I am worried that this coat/sticker is to protect the lens from scratching.
Please help to someone that bought the camera because he read good reviews on the camera capabilities.
Thanks
Take the protective sticker off, it's only there to protect it while in transit. No major manufacturer would put something so flimsy on a device and expect you to keep it on there full time.
I don't know if that's what is causing your problems for sure though. My G2 takes some great pictures, I'm really impressed with how well it does in low light. Then again, I'm coming from a Droid Bionic, so camera technology has had a couple years to improve.

Blurry images
Veapot thank you for the prompt reply.
Before I am removing the coat I am attaching an image of this coat to make sure that this is what you are talking about before I am removing it.
Did you remove the same one? Because I have to say that if it should be removed the manufacture did not make it easy to remove ...
Thanks again
FWIW, I just looked at my g2 and it looks exactly the same so I just tried to remove what does look like a blue/purple clear plastic protector with no luck at all, I think the color is the colour of the body surrounding the lens! So I have not tried anymore as damage is the only likely outcome!

Anyone have the same issue with pictures having weird pattern/marks?
Also there are lens flare on the third picture taken with oneplus 2. I took it again at the same position with my zenfone 2 without any lens flare problem, in fact i don;t have any lens flare issue like this with my zenfone2. It seems that one plus 2 camera is easier to have those lens flares maybe due its design (the distance between the glass, the lens and the sensor )??I don't know.... Im not familiar with optical physics..：p Is this a deflect with my camera or just a common issue with op2 camera?

It's common with ANY camera.
It all depends on the angle and distance between the glass that is used in the device.
You may not see it on your Zenfone 2 but given the right angle I can assure you it is there.. May not be as prominent but every camera has this.
My advice > Stop pointing the camera at light sources directly or shoot with RAW and post-process it out if you care that much.
Don't ask me how, Google it :silly:
Oh, forgot to mention you can try and cover the light glare using your hand above the camera but be sure to avoid making your hand visible in the shot and depending your angle and subject matter it may not be possible to do it anyway.
Like I said.. Best way to avoid it: Don't take pictures directly aiming towards light sources.
Thanks for your detailed explanation Stevels. I understand that lens flare is a common issue with any camera, what I want to express is it seems that one plus 2 camera is easier to have those lens flares maybe due its design (the distance between the glass, the lens and the sensor )??I don't know.... Im not familiar with optical physics..：p
Also with regrading to my 1st issue if you enlarge the first two pictures you can see weird pattern/marks on the sky, have you experience this before

Yeah, just a processing problem. Will probably be ironed out with future software updates.
To be honest I'm just waiting for CM12.1 to be released for the OPT.
Then I'll be grabbing the MaxxAudio and CameraNextMod apps and using those
Ordered my OPT a couple hours ago
Hi Everyone,
Have a look at attached example image to see what I mean.
Please try to take a manual shot with your wide lens in a very dark environment with very high ISO (3200 in example) and exposure time of 5secs plus (20 secs in example).
Everyone who has tried that so far has the same issue, a big purple shadow on the top. It's most likely the laser and it won't happen with the normal lense.
Do you have the same result? Any suggestions what we can do about it?
Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.) Unfortunately, image sensors are not hanging in space. They're packed in with a ton of other stuff. Stuff that gets warm. If that stuff is near an edge of the sensor, that heat bleeds into the sensor and then those warmed pixels get amplified by the higher ISO and next thing you know, Amp Glow. Well, that's the simplified version at least.
A cellphone, any cellphone, is not designed for those kinds of shots. If they were, they would have a tripod mount, a much better flash, and a much larger sensor. (Yeah, the flash on your cellphone is not meant to light up stuff much past 5 feet. Even the ones built into a DSLR aren't meant for much past about 15-20 feet.) The reality is that cellphones are designed for handheld shots with decent light. Even the larger sensor used in some cellphones shouldn't be expected to pull any miracles that top end DSLRs are just barely pulling off cleanly. For that shot, you would want to use a dedicated camera locked down on a tripod using base ISO and long exposure at the very least. Although, personally, I'd probably just take a pass on that shot.
someone on reddit has the exam same issue with the wide angle. and someone said it's in the regular too. weird. my s7 never had this purple hue when I did even 30 second exposure at night.

something obstructing the lens maybe, or just camera went bad
Better hope this isn't the same problem the HTC one m7 had with the purple haze. The culprit was a light sensor on the camera would overhear and give a purple haze on the screen in low light. Place the phone face down and with the camera on and see if the purple comes back.

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?

Settings aren't the only part of the equation. The other par is the placement of other components within the device. I need to look at the tear downs to see how the various parts are placed next to each other but something is heating up and passing that heat to the sensor. Just off the top of my head there are four parts together; the two camera sensors, the laser focus module, and the flask module. Each one of those on its own will generate heat if used enough.

It's the same issue. I haven't looked at the HTC issue but from your description of it, it's the same. Amp glow is what it is called in digital photography. (OK, silly that I said digital as you don't get amp glow in film.) The glow will show up because there is no other data coming off of the sensor for those pixels and the heat is amplified as "data".

Ok, just watched the JerryRigEverything repair tear down. The flash module sits right next to the wide angle and the laser focus next to the regular sensor. There is no mention as to what is sitting next to the sensors on the main board but I see silver boxes on each side with one having some sort of black and yellow warning sticker. Not sure what they are so I can't rope them in as culprits. So for now, I'd say it's a combo of the four units of the camera assembly.
Were you running the flash or one of the cameras a lot while you were playing around? Shooting a lot of long exposure shots in a row?
I'll get to test out some night shots and video tonight at a lighting ceremony but I'm still not expecting to shoot 3200 for 20 seconds type shots. Again, that's pretty extreme.
I have some concerns about the new Motorola G7 phones particularly:
Screen - The screen tends to have a blue/cool tinge, the overall display calibration is "off".
Camera - Colours can be washed-out, zoom has many artifacts & noise and poor dynamic range at night. Stabilization needs a lot of work (for both front & back) and overall sharpness/detail/colour could be better.
Does this mean the actual lens is of inferior make & quality?
Will a GCam port be enough to compensate for the otherwise poor camera image quality?
Need help. Thank you.
Unlike G6 and Z3 Play, you cannot change the color temperature.
However, you can install CF Lumen if yours rooted.
I did it on both G6 (compensate green) and G7 to keep the color temperature consistent.

For the screen, I usually use night light. Corrects it easily
I know our maintainer is working on a gcam port last I knew. If you have twrp you can always flash gapps with gcam
But to answer the thread title: no its not worse with more RAM, more storage, better SoC, etc than the g6

I haven't noticed where the screen seems to be blue, mine looks fine to me and other colors seem just fine.
As far as zoom goes this device does not have optical zoom, so of course it's going to be bad. May as well take picture normal then crop, it achieves the same thing. I think stabilization is amazing, definitely a lot better than the G6.
I use the Google Camera port and it definitely takes good pictures but I haven't noticed and differences between them. Night sight is amazing too.

I have a replacement screen and the video looks fabulous over my g4. That died. Get a case or you're going to be looking on eBay for a picture of the exact same ribbon cable printing for about 29 bucks. If the photo doesn't show same printing on the black, don't get it! Real on left, not gorilla glass 3 on the right. I used silicone on the very edges instead of getting that 3M stuff because this model of phone uses the REALLY thin stuff. Did my pic upload?
Absolutely NOT! I feel as though the G7 is USA's G7 Plus with those specs. Lenovo really screwed up not bringing the G6+ to the USA last year. My OG Pixel was trashed (throwing it at a concrete wall) and my closest option to purchase an Unlocked Device was at Walmart. All the devices they had on display were last years models and the very non-knowledgeable sales Rep didnt know what was in stock, so i said forget the display models and lets head over to the storage box and see what there is to choose from. When he opened the box, a bright light shined over and they're were about 8 G7s (non of which was on display). "Oh we cant sell them yet" WTF??? Go I got stuck taking a G6, but I was NOT a happy customer. Contacted Walmart Customer Support and 2 days later i returned the G6 for my awesome Moto G7.

I do repairs so I see complaints about color accuracy on devices all the time, but you can take devices straight out of the box and there will be variations because there is an acceptable tolerance otherwise they'd be throwing out so many screens. The ones that tend to get the most complaints are the ones at the edge of the tolerance.
3m tape is awful for screen replacement, we use the black Tessa tape, it's super sticky and doesn't like to let go.
